Find the optimum liquid concentration of the propane-isobutane mixture in an auto- refrigerated alkylation reactor. The exothermic heat Q. (106 Btu/h) of the alkylation reaction is removed by vaporization of the liquid in the reactor. The vapor is com- pressed, condensed, and flashed back into the reactor through a pressure letdown valve. The reactor must operate at 50°F, and the compressed vapors must be con- densed at 110°F. Find the liquid mole fraction x of propane that minimizes the compressor horsepower requirements for a given QR. Assume the compressor adiabatic efficiency is 100 percent.
